SHEAF CARRIER AND ELEVATOR FOR THRESHING-IVIACHINES.

Specification of Letters Fatent.

Patented Feb. .19, 1907.

Original application filed October 14, 1904, Serial No. 228,446. Dividedand this application filed January 26, 1906. Serial No. 298.040.

To all whom it may concern.-

Be it known that I, RICHARn'SYLvEsTER, of Lindsay, in the county ofVictoria and Province of Ontario, Canada, have invented certain new anduseful Improvements in Sheaf Carriers and Elevators for Threshing-Machines, this being a division of my application for Letters Patent ofthe United States, Serial No. 228,446, filed October 14, 1904; and Ihereby declare that the following is a full, clear, and exactdescription of the same.

This invention relates to a sheaf basket and elevator forthreshing-machines in which the sheaves can be deposited to beautomaticaliy conveyed to the feeder for delivery to the band-cutter andcylinder during the op eration of the separating mechanism; and theinvention consists, essentially, of a sheafbasket connected to theframing of the separator and adjacent to the feeder mechanism, and anelevator operating in the sheaf-basket and driven from thecylinder-shaft to automatically seize the sheaves and carry them fromthe bottom of the sheaf-basket to the top thereof, so that the sheavescan fall by gravity on the feeder-belt, as hereinafter more fully setforth, and more particularly pointed out in the claim.

For a full understanding of the invention reference is to be had to thefollowing description and to the accompanying drawings, in which Figure1 is a side elevation of a threshing- Inachine, showing the constructivearrangement of the parts. Fig. 2 is a vertical transverse section on theline a a, Fig. 1. Fig. 3 is an enlarged perspective view of the sheafbasket and elevator. Fig. 4: is a perspective view of a section of theupper elevator-shaft and one of the sides for the back of thesheafbasket, and Fig. 5 is a similar view of the lower elevator-shaftand one of the sides for the sheaf-basket bottom.

Like characters of reference indicate like parts throughout thespecification and drawings.

Connected to each side of the framing of the separator 1) adjacent tothe top of the feeder sides I) are two bearing-brackets h, and journaledin the brackets h is a sprocketwheel shaft 71, driven from thecylinder-shaft j by a motion-transmitting means it.

Articulatingly suspended from the sprocket-wheel shaft h are the sides76 of the sheaf-basket back 76, to be selectively moved into asubstantially vertical position against the framing of the separator orinto an inclined position, as shown in Fig. 3. Journaled in the sides 7:is a sprocket-wheel shaft Z, and articulatingly mounted on thesprocket-wheel Z are the sides 1 of the bottomfof the sheaf-basket. Asshown in Fig. 3, the sides 1 can be extended at an angle from the sides7c when the parts are in their operative position to receive and holdthe sheaves deposited in the sheaf-basket, or they can be folded againstthe sides 7c, and the lastnamed sides can be moved int-o a substantiallyvertical position against the framing of the separator when the partsare not muse.

The sheaf-basket back 7c is shown in the drawings to be containedbetween the sheafbasket sides and is employed to prevent the sheavespassing from the sheaf-basket througn the intervals existing between theelevatorbelts as they are carried by pivoted fingers q andelevator-belts p to the feeder-belt s, and the sheahbasket bottomfisemployed to pre vent the sheaves falling from the sheaf-basket whileawaiting seizure by the pivoted fingers. Detachably connected to theframing of the separator b and to the sides 76 are braces l" to hold thesheaf-basket parts in their extended position, as shown in Fig. 3.

Mounted on the sprocket-wheel shafts h and l are sprocket-wheels 0 andm, and traveling around the sprocket-wheels 0 and m are elevator-belts7), having pivoted fingers g to seize the sheaves within thesheaf-basket and carry them to the top of the elevator-belts as theelevator-shafts revolve and deposit the sheaves on the feeder-belt s.The feederbelt 8 is driven from the cylinder-shaft by the usualtransmission means. By driving the elevator-shaft h from thecylinder-shaft j it is possible to regulate the speed of theelevator-belts to that of the feeder-belt, so as to maintain a deliveryof the sheaves from the sheaf-basket to the feeder-belt consistent withthe working speed of the threshing mechanism. During the revolution ofthe cylinder-shaft j motion is imparted by the transmission means h tothe elevator-shaft h and the sprocket-wheels thereon to drive theelevator-belts p, so that when the fingers come into position on theupper side of the belts as the latter passes around the sprocket-Wheelsm they Will seize the sheaves Within the sheafbasket and securely holdthem as they move to the top of the elevator, Where they are depositedon the feeder-belt 5. By having the sheafbasket sides 7r articulatinglysuspended from the elevator-shaft h and the sheaf-basket sides 7"articulatingly mounted on the sprocket-Wheel shaft 1 it is possible tofold the sides 1" and bottom f of the sheaf-basket against the sides lcand back and then position the sides 7r: and the back against theframing of the separator, so that the entire Width of the apparatus whenthese parts are in their inoperative position Will not materially exceedthe Width of the truck, the pivoted fingers q When parts of thesheafbasket are folded lying close to the sprocketchains.

Having thus fully described my invention, What I claim as new, anddesire to secure by Letters Patent, is -,t In a threshing-machine thecombination of an elevator-shaft j ournaled in bearings connected to theframing of the threshing-ma chine, a sheaf-basket back, sides for thesheaf-basket back articulatingly suspended from the elevator-shaft, anelevator-shaft journaled in the said sides, asheaf basket bottom, sidesfor the sheaf-basket bottom articulatingly mounted on the last-mentionedelevator-shaft so that the sheaf-basket bottom can be folded against thesheaf-basket back or extended at an angle thereto, elevator- Wheelsmounted on both of said elevatorshafts, elevator-belts passing aroundthe elevator-Wheels, elevator-fingers carried by the elevator-belts, andmeans for revolving the first-mentioned elevator-shaft and causing thetravel of the elevator-belts.
